Hans-Michael Klein, chairman of the society, told the BBC that this practice creates discomfort for many Germans, who are more used to just shaking hands. Although the society cannot officially ban it, “We have to protect people who don’t want to be kissed,” Klein said. “So we are suggesting that if people don’t mind it, they announce it with a little paper message placed on their desk.”

He said he received 50 emails this year alone to complain about kissing as a greeting at work. “[The custom] has come from places like Italy, France and South America, and belongs in a specific cultural context. We don’t like it, they say.” Klein also said the acceptable social distance in Europe is 23 inches apart.
